Specification of Letters Patent.

Application filed May a1, 1918. Serial no.- 237342.

To all whom" it may concern:

. Beit known that I, RAYMOND PAUL, a citizen ofthe United States,residing at Chicago, in. the county-of Cook and State of Illinois, haveinvented certain new and useful Improvementsjin Stylus-Holders, of whichthe following is a specification! This invention relates-to talkingmachines and has for its object the provision of means on the soundboxor'reproducer wherebythe stylus may be readily'inserted and removedwithout the necessityof manipulating-screws or other fasteningmeans.

QA furtherobject of my invention is the provision of; means whereby. myimproved stylus holder "is-readily adaptable to sound boxes of usualconstruction 'without inter fering with or :modifying the .fstru'cturethereof..-

Further objects and advantages of my invention reside :in' the variouscombinations herein-afterclaimed as will be better understood; 6yreference tothe. following specifi- Qationwhen-read'in connection withthe ac- J25 compan' in drawing illustratingthe preferred eihb dimentsthereof, in which-e Figure 1 is aside elevation of a sound box embodyingmy invention;-

Fig. 2 isv an enlargeddetail in section of the invention;

Fig; 3 is a section on the line 33 of s- Fig. 4 is an enlarged detail insection of a slightly difl'erentform of my invention, and v A Fig. 5, isa section on the line 5-5 of ig. 4. I

Referring to the drawing, 5 indicates a sound box of any. suitable orusual form of construction carrying a pivoted stylus lever 6'whi ch isconnected at one endto the diaphragm 7 and at the other end is providedwith'an enlarged head. 8 having a socket to receive the stylus 9. Thehead 8 1S grooved to receive a spring10- which isfastened atone endtherein .andwhich at its other end bears a ainst a ball 11 in a recess12 connecting with the groove and socket in the head. A- ;eover' plate13 is fastened by, screws or other suitable means to the head 8 andconceals the springv 10.

a The ball 11 is normally held by the spring 10 so that it protrudesinto the socket. in the 1 head 8'. When the stylus 9 is inserted in thesocket it engages the ball, 11 and forces the spring 10 outwardly.- Theball permits easy insertion'and withdrawal of the stylus and the springclamps the stylus between the ball and the opposite side of the socket,holding it firmly'in position to cooperate properly with the recordduring the reproduction.

In Figs. {land 5,- I have, illustrated a slightly different form of myinvention intended for use in adapting my invention to common forms. ofsound boxes without changing or modifying their construction. In-thisform of my invention the usualclamping'screw isremovedfrom the head 14and the stylus lever and the supplemental head 15 is secured thereto bymeans of a screwf16' which engages the opening pro vided for theusual'clamping screw The supplemental head 15, which forms an extensionof the head 14, is provided with a socket which alines with the socketin the head The supplemental head 15 is grooved to receive a spring 17,one end of which is secured to the supplemental, head while the otherbears against a ball 18 disposed in an opening communicating with thesocket and groove. A plate 19 secured to the supplemental head by screwsor other fastening means covers the spring 17 The mode of operation ofthis form of my invention is identical with that of the form previouslydescribed. The stylus is held in the socket by the operation of thespring 17 which firmly'clamps the stylus between the ball 18 and theopposite side of the socket. The stylus may be easily inserted andwithdrawn, the operation being facilitated by the ball 18 which revolvesas the stylus is moved in or out of socket.

From the foregoing it will be readily understood that I have perfected anovel means for holding a stylus in the talking machine which dispensesentirely with the usual clamping screw. This screw is small anddiflicult to manipulate; may become loose or misplaced and frequentlydoes not grip the stylus with suflicient rigidity to" lnsure properreproduction if carelessly handled.

.My improved stylus holder insures gripping of the stylus with the samedegree of pressure which is sufiicient to hold it'in proper relation tothe stylus lever during the reproduction.

Various changes maybe made in the form, arrangement and construction ofthe parts without departing from the spirit and scope. 110 I of theinvention or material advantages,

described being merely .bodiment thereof.
